Given a quadratic function, find the inverse and determine if a function or not

The video tutorial covers the process of rewriting a function as y, swapping variables, and solving for X using inverse operations. It emphasizes the importance of introducing the square root with plus or minus and explains the distributive property for division. The teacher discusses the concept of functions and inverse functions, highlighting that an inverse function may not always be a function if it yields multiple y-values for a single x-value.
